This is the case that the unit space is defined at the edge of total space. There are two types of this. One type is to predict or unusualness, for example prediction of an earthquake or diagnosis of various diseases. The other type is to identify an individual person from a picture or to identify a handwriting word. The first type is to find or to predict unusual risky event and the second type is an identification of each person. This chapter explains a general methodology and Chapter 9 will explains the former and Chapter 12 the latter.
